Fears grow for trapped UK miners

Fears are growing for the safety of two Britons among the 29 men missing after an explosion in a New Zealand coal mine as rescuers remain unable to enter.

Peter Roger, 40, and Malcolm Campbell, 25, are from Scotland, the Foreign Office confirmed.

David Cameron and Prince William have both contacted New Zealand’s Prime Minister John Key offering support.

There are fears of a second explosion at the West Coast’s Pike River mine after tests showed gas levels rising.

Mr Roger, a former Perth Grammar pupil, emigrated to New Zealand two years ago to be closer to his mother and sister who live there, according to the Courier newspaper.

He was formerly an offshore oil engineer.

Gary Fraser, a friend of Mr Roger, told the BBC he was a “strong character” and that this was the second time he had been trapped in recent months.

The parents of Mr Campbell, from St Andrews in Fife, said they had to keep hoping for good news.

In an interview broadcast on STV News, his father Malcolm said: “We can’t concentrate on anything, we can’t sleep because it’s difficult.

“Our prayers and thoughts go out to everybody who is going through this in New Zealand. We just keep hoping that everything will be fine.”

The miner is due to marry his fiancee, Amanda Shields, 23, on 18 December.

There has been no contact with the miners since an explosion around 1530 local time (0230 GMT) on Friday.

A Foreign Office spokesman said both the UK miners are residents in New Zealand and their families had been offered consular assistance.

Prince William’s message came in the form of an email.

A Clarence House spokesman explained: “William has been to New Zealand on several occasions and is very fond of the country. He wanted to send a message of support.”

A mine expert says any attempt to rescue men trapped in a New Zealand mine is hampered by fears for the safety of the rescuers

UK Prime Minister David Cameron, who is in Lisbon for the Nato summit, is being kept informed of developments, Downing Street said.

“Clearly he is deeply concerned about the appalling situation there. Clearly we stand ready to provide any assistance that is required,” a spokeswoman said.

The PM has sent a text message to his New Zealand counterpart John Key, which read: “I am thinking and praying for the best. I will make sure our diplomatic team help in any way they can”.

Foreign Secretary William Hague said the British high commission in New Zealand was working with the New Zealand authorities to help to contact relatives locally and in the UK.

“It is a very worrying situation and we will do our utmost to assist,” he told Sky News.

Tests showed an underground fire was burning at the mine, the company’s chief executive Peter Whittall said.

“Samples we took do indicate that we’ve got a heating of some sort underground, that means that there’s some combustion of material generating the gases that go with that,” he said.

The missing workers range in age from a 17-year-old – believed to be on his first shift – to a 62-year-old.

Each miner carried 30 minutes of oxygen, enough to reach oxygen stores in the mine that would allow them to survive for several days, officials from Pike River Coal, the mine operator, said.

Andrew Watson of the Mines Rescue Service, in the UK, said rescue efforts would be frustrated by fears for the safety of the rescuers themselves.

He said the trapped men would have been “trained to barricade themselves into somewhere where they are safe”.

To let rescuers know they are still alive, he said the best way would be to “hit solid strata”. Above ground a listening device, called a geophone, would detect that signal, he said.

The natural hazards associated with coal mining include the build-up of methane and the risk of spontaneous combustion.

With an explosion inside a mine, transport, communication, ventilation and the means to monitor conditions inside the mine would be disrupted or lost, Mr Watson said.

This means monitoring is restricted to very close to the mine surface. “They won’t have enough confidence in the information they’re getting to deploy the [rescue] teams,” he said.

The mine, which employs some 150 people, has been operational since 2008 and runs deep under the Paparoa Ranges on the rugged western coast of the South Island.

Of the 29 men, 16 are local employees, while 13 are contractors. Two are thought to be Australian.

An electrician went into the mine at 1550 local time to investigate a power failure, and 1,500m (4,920ft) into the shaft he discovered the driver of a loader who had been blown off his machine. He then raised the alarm.

Mining experts said it could have been an explosion of methane gas, coal dust, or a combination of the two.

Labour ‘may back’ detention cut

Ed BallsThe move would be a major shift in policy from Labour’s time in government
Related stories

Shadow home secretary Ed Balls has said Labour may be ready to back coalition moves to cut the pre-charge detention period for terror suspects to 14 days.

In a major policy shift, he said he could support changes if they did not impede police and security services.

Mr Balls told the Sunday Telegraph Labour’s reputation had suffered from its attempts in government to raise detention times to 90 and then 42 days.

The coalition has also said it wants to review control orders.

Home Secretary Theresa May announced a review of counter-terror legislation in June, when she said her personal view was that the limit should be 14 days, which the Liberal Democrats also support.

The review, overseen by former director of public prosecutions and Lib Dem peer Lord Macdonald of River Glaven, is still under way.

“Even 42 days was a step too far – our reputation as a party which protected liberty as well as security suffered as a result”

Ed Balls Sunday Telegraph interview

It is also considering the issue of control orders – introduced under 2005 anti-terrorism legislation – which Mr Balls said he was also prepared to see scrapped if there was a workable alternative.

Ministers sign an order to place a terrorism suspect under close supervision that some say is similar to house arrest.

The government said at the time that it still needed a mechanism which would allow it to control the lives of some suspects whom it said it could not prosecute because of the rules over the use of secret intelligence in trials.

In 2005, under prime minister Tony Blair, Labour tried to raise the time terror suspects could be held without charge to 90 days – resulting in Mr Blair’s first Commons defeat as PM.

MPs later voted to extend the period from the then limit of 14 days to 28 days.

There was a further attempt to raise it to 42 days under Gordon Brown, in 2008, but the plan was heavily defeated in the House of Lords, and then abandoned.

Mr Balls admitted in the Sunday Telegraph interview that those attempts got the balance wrong between protecting the UK from the risks of terrorist attacks, and preserving democratic freedoms.

Mr Balls told the paper: “Even 42 days was a step too far. Our reputation as a party which protected liberty as well as security suffered as a result.

“Our approach should always be that if the evidence shows we can go down from 28 days without impeding the police and security services from doing their jobs, then we ought to do it.”

“Even the authoritarian Labour Party which introduced 28 detention now agrees that it’s wrong”

Alex Deane Big Brother Watch

On control orders he said: “They are such exceptional measures that in an ideal world of course we would want to manage without them,” he said.

On both issues Mr Balls’ final stance will depend on the evidence of the police and the security services to the government’s review, he said.

He made clear his intention to move away from what was seen by some critics as an authoritarian approach under Mr Blair and Mr Brown.

“In government, I’ve no doubt that my Labour colleagues did their best on every occasion to get that balance right in the face of the real and dangerous threats against the country, but did we always succeed? Probably not.”

This change of heart is likely to go down well among Labour’s supporters – many of whom regarded the detention time limits as draconian, said BBC political correspondent, Gary O’Donoghue.

Civil liberties campaign group Big Brother Watch said the government should now debate whether to go lower than 14 days.

Director Alex Deane said: “This is good news. It means that there is simply no excuse for the government to keep the limit at 28 days – even the authoritarian Labour Party which introduced 28 detention now agrees that it’s wrong.”

Lib Dems ‘broke no fees promise’

Vince CableMr Cable says his party is bound by the coalition agreement – not its election manifesto
Related stories

Business Secretary Vince Cable has denied breaking promises on university fees, insisting the Lib Dems’ pledge to oppose any rise was not binding.

Signing such a pledge on fees before the election might have been the wrong “political judgment”, he acknowledged.

But Mr Cable told BBC1’s Politics Show coalition plans to lift the ceiling on tuition fees to £9,000 did not indicate his party was untrustworthy.

Labour has attacked the Lib Dem U-turn, which provoked angry student protests.

Thousands of people took to the streets of London for a demonstration earlier this month, which flared into violence when a 2,000-strong section of the march broke off to confront police and attack the Conservative party headquarters.

The National Union of Students has also vowed to “chase down” any Liberal Democrat MPs who vote in favour of allowing universities in England and Wales to increase fees from the current cap of £3,290.

Many had publicly signed a pre-election pledge to vote against any such rise, should they be elected in May.

But Mr Cable insisted his party had not betrayed anybody and that the coalition agreement struck with the Tories was their only binding commitment.

“We didn’t break a promise. We made a commitment in our manifesto, we didn’t win the election. We then entered into a coalition agreement, and it’s the coalition agreement that is binding upon us and which I’m trying to honour,” he said.

“A lot of the people who are protesting actually don’t understand what’s being proposed”

Vince Cable Business Secretary

Asked whether it would have been better if he had not signed the pledge, he added: “From the point of view of political judgment it may well have been, but it’s not an issue of trust.

“We and the Conservatives separately made a whole series of commitments in our manifesto and outside it.

“We haven’t been able to carry all of them through, partly because we have a coalition and have had to make compromises and partly because we’re still in the middle of this appalling financial situation.”

Deputy Prime Minister Nick Clegg was bombarded with parliamentary questions on the subject earlier this month.

Labour’s deputy leader Harriet Harman quoted him as having previously said that increasing tuition fees to £7,000 a year would be “a disaster” and described the new stance as “shameful”.

Mr Clegg, the Lib Dem leader, insisted the coalition’s policy – due to take effect from 2012 – was fair and that graduates who earned the least would pay less than currently.

Student protestThousands of people have protested against the fee hike

However, he has admitted that he “should have been more careful” about signing the pledge in common with other Lib Dem MPs.

Amid expectations of further protests on Wednesday, Mr Cable told the BBC that many of those involved did not grasp what the government was proposing.

“It doesn’t actually affect them – we’re talking about a system of graduate contribution that will only affect people who start going to university in a couple of year’s time,” he said.

“If they are concerned for the next generation what I think they do need to understand is that we’re making the system significantly fairer, making it much more attractive for part-time students and for graduates on low incomes.”

‘No decision’ over RAF Leuchars

RAF LeucharsAbout 1,200 people are employed at RAF Leuchars in Fife

The Ministry of Defence has said that no decision has been made regarding the future of RAF Leuchars in Fife.

The comment comes amid reports that the airbase, which employs 1,200 people, could close to save a base in Moray.

Last month it was announced that RAF Kinloss in Moray would shut after ministers cancelled orders for the new Nimrod MRA4 surveillance aircraft.

The future of neighbouring RAF Lossiemouth is unclear. The closures stem from the strategic defence review.

In a statement, the MoD said: “The strategic defence and security review means that Kinloss and two other bases will not be required by the RAF.

“No decisions have been made on which bases or on any future use.”

The uncertainty about RAF Leuchars in Fife comes after reports in the Scotsman newspaper suggesting the base could be “sacrificed” to save RAF Lossiemouth.

Sir Menzies Campbell, who represents North East Fife, said RAF Leuchars was “vital” for the defence of the UK.

He said: “Well I know that the Ministry of Defence is conducting a wholesale review.

“But when it comes to Leuchars, the strategic case for the retention of Leuchars is absolutely overwhelming.

“Not least because it has just received the first of the three typhoon squadrons that was promised to it.”

Sir Ming said £40m had already been spent on the base preparing for the arrival of the typhoons.

He added: “The runway’s been resurfaced and there is no strategic case in my view of any kind whatsoever for taking Leuchars away from doing its job, which is to protect the airspace of the northern half of the United Kingdom. And it does that on a regular basis.”

Scottish Labour leader Iain Gray said the uncertainty surrounding Leuchars was “extremely worrying” for people in Fife.

He added: “Scotland has already lost one airbase to the Tory-Liberal government and there is no case to lose another.”

Westminster SNP leader and Moray MP, Angus Robertson said the review was nothing but a “finance driven sham”.

A final decision on the future of the bases is due to be announced early next year.

Energy firm oil plan secrecy fear

Cairn workersCairn Energy is looking to develop oil fields in the Arctic off Greenland
Related stories

The Scots-based energy firm involved in oil exploration in the Arctic has refused to publish full details of its contingency plan should a spill occur.

Cairn Energy, based in Edinburgh, is at the forefront of the push to open up oil supplies off Greenland.

The company and the Greenland government told a BBC Scotland investigation team the plan was secret to prevent sabotage by “third parties”.

The lack of transparency has prompted concern from environmental groups.

Some estimates have suggested that the Arctic region could contain up to a quarter of the world’s remaining oil reserves.

Cairn is due to resume its operations in the region next spring after spending the summer carrying out exploration work.

Dr Martin Preston, a marine pollution expert at the University of Liverpool, said the plans that were currently in the public domain gave little detail about how Cairn would deal with a spill.

He said: “I think they are making comments about using really rather standard techniques which are employed elsewhere and I’m not sure they’ve really taken on board some of the risks that are associated with this high latitude work. And that worries me.”

In August, protesters from environmental group Greenpeace tried to stall the exploration work by occupying Cairn Energy’ s Alpha rig.

The protest ended in September following the arrest of four activists.

Greenpeace spokesman Ben Ayliffe said it was ludicrous to infer his organisation could sabotage any attempt to clean up a future oil spill.

“It’s more important that the response plans work and are efficient than having everyone know phone numbers and where exactly the equipment is situated and so on”

Jon Skov Neilsen Greenland government

He said: “Greenpeace have been out in Greenland taking peaceful direct action to stop companies like Cairn drilling in the first place.

“It is completely absurd to suggest and completely wrong to suggest that Greenpeace would somehow stop Cairn from actually trying to stop a well leaking if that ever happened.”

Cairn Energy has insisted they have filed a detailed spill plan with the government of Greenland.

During drilling operations, the company said they had two rigs working together, which allowed them to drill a relief well in case of any blow-out, as well as a fleet of support vessels.

Simon Thomson told the BBC his firm was focused on safety.

He said: “Everything that we have done, we have done in conjunction with the authorities and they quite rightly have a challenging regime, so they’ve adopted Norwegian North Sea standards which are kind of the toughest in the world.”

Mr Thomson said there had also been “third party reviews” of the company’s safety plans.

He added: “So, yes, we are very confident that we have got a robust drilling programme.”

Jon Skov Neilsen, head of Greenland’s bureau of minerals and petroleum, added: “It’s more important that the response plans work and are efficient than having everyone know phone numbers and where exactly the equipment is situated and so on.

“That’s our view anyway. That’s the choice we’ve made and we think it’s the right choice.”

Chihuahua joins Japanese police force

Momo poses during a police dog examination held at Koriyama, western Japan (file picture)Momo will begin her rescue work in January

A chihuahua named Momo (Peach) has passed the exam to become a dog in the police force in western Japan, in what seems to be a first.

The 3kg (6.6lb) dog is set to become part of a search-and-rescue team used for disasters such as earthquakes.

Its small size means it will be able to squeeze into places too narrow for traditional rescue dogs, such as German Shepherds.

Chihuahuas, named after a Mexican state, are the smallest breed of dog.

“It’s quite rare for us to have a chihuahua work as a police dog,” said a police spokeswoman in Nara, western Japan.

“We would like it to work hard by taking advantage of its small size.”

Momo, aged seven, will begin work in January.

Plain cigarette packets proposed

Cigarettes in a packetThe government is considering making all cigarettes packets plain brown or grey
Related stories

Cigarette packets should have plain packaging to make smoking less attractive, ministers have suggested.

The government is currently planning to ask retailers to cover up their displays of cigarettes from next year to protect children.

But now cigarette packets could also be made a standard colour like grey, rather than the existing bright colours.

Campaign group ASH says this is “an enormous leap forward”.

The Department of Health is considering the idea of asking tobacco firms to put only basic information and health or picture warnings on their packets.

Making the cigarette packets a plain colour would protect children from taking up smoking in the first place, it suggests.

It would also help support people who are trying to give up smoking, the department said.

Health Secretary Andrew Lansley, said it was time to try a new approach.

Young smoker

“The industry use packaging to seduce our kids and mislead smokers”

Martin Dockrell ASH

“The evidence is clear that packaging helps to recruit smokers, so it makes sense to consider having less attractive packaging. It’s wrong that children are being attracted to smoke by glitzy designs on packets.

“We would prefer it if people did not smoke and adults will still be able to buy cigarettes, but children should be protected from the start.

“The levels of poor health and deaths from smoking are still far too high, and the cost to the NHS and the economy is vast. That money could be used to educate our children and treat cancer,” Mr Lansley said.

“We will shortly set out a radical new approach to public health in a White Paper.”

Martin Dockrell, director of policy and research at ASH, (Action on Smoking and Health), said the industry calls packaging “the silent salesman”.

“They use it to seduce our kids and mislead smokers into the false belief that a cigarette in a blue pack is somehow less deadly than a cigarette in a red one.

“By helping smokers who want to quit and protecting our children from the tobacco ad men this will be an enormous leap forward for public health, perhaps even bigger than the smoking ban,” he said.

“The government accepts that packaging and tobacco displays influence young people, so there is no time to waste. It may take years to pass a new law on plain packs but the law on tobacco displays is already on the statute books and comes into force next year.”

Recent research published in Tobacco Control showed that putting tobacco out of sight in shops not only changes young people’s attitude to smoking, it also doesn’t result in retailers losing money.

UN urges tobacco additive limits

A young man smoking outside a pubThe guidelines aim to help reduce the numbers of young smokers
Related stories

A conference on tobacco held in Uruguay has recommended that additives used to make cigarettes more appealing to new smokers should be restricted or banned.

Delegates from over 170 countries that have signed a UN tobacco control treaty also said tobacco producers should disclose their products’ ingredients.

These guidelines – adopted by consensus – represent the latest public health setback for the tobacco industry.

WHO figures point to huge losses of life from tobacco use.

The World Health Organisation says that tobacco kills more people than Aids, legal drugs, illegal drugs, road accidents, murder and suicide combined.

It estimates that of the more than six billion people alive today, half a billion will eventually be killed by tobacco.

A spokesman for the WHO’s Framework Convention on Tobacco Control, Tarik Jasarevic, told the BBC the industry had lobbied hard against the latest measures.

Mr Jasarevic suggested the delegates wanted to make it harder for the industry to target young people.

“The parties feel that from the point of view of public health, there is no justification to use ingredients that increase the attractiveness of tobacco products, that in turn increase the number of new smokers, especially among young people,” he said.

The guidelines would now be used by national governments to draw up legislation, he said. But he added that there was no specific timetable for them to do so.

The head of the International Tobacco Growers Association, Antonio Abrunhosa, criticised the decision.

It allowed governments great leeway in deciding what measures to take, he said.

And he told the AFP news agency that if one popular blend – American – was banned, “it will impact more than 6m producers worldwide”.

NZ rescue attempt ‘still unsafe’

Peter Whittall

Pike River Mine Chief Executive, Peter Whittall, says the hole will be used initially for taking gas samples

Related stories

Latest tests on gases show it remains unsafe to attempt the rescue of 29 men trapped after an explosion at a mine in New Zealand, officials say.

A drilling rig has been brought to the site and rescuers will start to drill a new hole on Sunday to carry out further tests.

The police chief in charge said he was still optimistic and that this remained a rescue operation.

There has been no contact with the men since they were trapped on Friday.

Pike River Mine Chief Executive Peter Whittall told a news conference on Sunday the latest tests had shown there was still heat being given off underground.

Carbon dioxide, methane and other dangerous gases were still being generated but there was no evidence of a big fire, he said.

Mr Whittall said a drill rig had been mobilised and would try to sink a small hole to a depth of 100m-150m, with the intent of hitting the underground roadway.

He said it could take between 16 and 20 hours, depending on drill reliability and the topography.

“If we can make the hole big enough, we have some opportunities to put other devices into the mine,” he said, without elaborating.

Fresh air is being pumped into the mine through a shaft.

Regional police commander Gary Knowles said the families of the missing men were “distraught” but understood the situation.

He said no rescuers could be sent into the mine unless it was safe.

New Zealand’s PM John Key has said bringing the men out of the Pike River coal mine remains his top priority.

He said his government was “doing what we can to make sure these 29 brave men are taken out of the mine and are here in one piece”.

“This is a time of huge anxiety for the families and for the miners, so our heart and thoughts go out to them,” he said.

The explosion at the Pike River mine is believed to have happened at about 1530 (0230 GMT) on Friday.

An electrician went into the mine at 1550 to investigate a power failure, and 1,500m (4,920ft) into the shaft he discovered the driver of a loader who had been blown off his machine. He then raised the alarm.

Mining experts said it could have been an explosion of methane gas, coal dust, or a combination of the two.

The missing workers range in age from a 17-year-old – believed to be on his first shift – to a 62-year-old.

Cross-section of the Pike River mine

Mr Knowles said that there were 24 New Zealanders, two Australians, two Britons and a South African national.

Britain’s Foreign Office later confirmed that two Britons had been reported missing in the incident. It said both men were from Scotland.

1939: Carbon monoxide asphyxiates 11 men at Glen Afton mine in Huntly

1967: Gas explosion kills 19 miners at Strongman mine, near Greymouth

Each miner carried 30 minutes of oxygen, enough to reach oxygen stores in the mine that would allow them to survive for several days.

The mobile phone of one of the men was said to be still working, but was not being answered when called.

Mr Whittall said there were also supplies of water underground and the temperature was about 25C.

He said that until the location of the missing men could be confirmed, the structure of the mine meant it was not possible to send supplies down “with any certainty as to where it’s going”.

Two workers who walked out of the mine have been treated in hospital for moderate injuries but have since been discharged.

Officials said one of the men had been very disorientated when he emerged. The other was able to speak to officials and said he believed he had been knocked over by a blast, causing him to briefly lose consciousness.

US bodies found in tree ‘stabbed’

Matthew Hoffman, in a booking photo from the Knox County sheriff's officeMatthew Hoffman, 30, is being held on a kidnapping charge
Related stories

Three people whose bodies were found in a hollow tree trunk in the US state of Ohio were stabbed to death before they were dismembered, a coroner has said.

Tina Herrmann, son Kody Maynard and her friend Stephanie Sprang were stabbed several times in the back and chest.

The bodies were later cut up, placed inside rubbish bags and lowered into the hollow of a large tree in a wildlife reserve, the coroner said.

The only suspect in the killings is being held on a kidnapping charge.

He is Matthew Hoffman, an unemployed tree surgeon and ex-convict.

The victims died sometime on 11 November and there were no signs of sexual assault, the coroner added.

Mr Hoffman gave information through his lawyers which led officers to the bodies, which were found on 18 November.

He was arrested after Tina Herrmann’s daughter, Sarah Maynard, 13, was found bound and gagged in his basement on Sunday, and he is now being held on kidnapping charges.

She was reported missing on 10 November, along with Tina Herrmann, 32, her brother, Kody Maynard, 11, and Stephanie Sprang, 41.

Mr Hoffman, who served time in prison in the state of Colorado for arson and other charges, has not yet entered a plea to the kidnapping charge.

Poo and paws help in tiger count

Tiger pugmark (Image: Yadvendradev Jhala)While paw prints can identify individuals, scientists say the method is unreliable for assessing numbers
Related stories

A system that uses paw prints and faeces offers scientists a fresh way to determine how many tigers are left in the wild, a study has suggested.

Scientists hope the new technique will provide a low-cost and reliable way to accurately assess big cat numbers.

Fewer than 3,500 tigers remain in the wild, with more than half found in India where the population is spread over more than 100,000 sq km of forest.

The findings appear in the Journal of Applied Ecology.

“Tigers are cryptic, nocturnal and occur at low densities so they are extremely difficult to monitor,” said lead author Yadvendradev Jhala from the Wildlife Institute of India.

“Unless we know how many tigers are left in the wild, and whether their numbers are increasing or decreasing, we will not be able to conserve them,” he added.

Current monitoring methods include using camera traps or looking for paw prints.

“In the absence of abundance information, conservation management decisions are often based on crude estimates, expert opinion or educated guesses – which may result in erroneous decisions that can be counterproductive,” the India-based team observed.

While paw prints, otherwise known as pugmarks, allow individual tigers to be identified, scientists say they are not a reliable way to estimate a region’s overall population.

Camera traps offer a much more accurate assessment of an area’s tiger density, but the technique is expensive and labour intensive, resulting in its deployment being limited to places that have a relatively high number of the big cats.

‘Basmati rice’

“By showing that it is possible to accurately estimate tiger numbers from their paw prints and faeces, we have opened up a new way of cost-effectively keeping our finger on the pulse of the tiger population and gauging the success of conservation programmes,” explained Dr Jhala.

“Fresh tiger faeces are normally accompanied by urine sprays that smell like well-cooked basmati rice”

Dr Yadvendradev Jhala Wildlife Intitute of India

“This approach could be applied to monitoring other endangered species across vast landscapes,” he added.

Between 2006 and 2007, Dr Jhala and his team gathered samples from 18 tiger populations at 21 locations across central and northern India, recording the occurrence of pugmarks and faeces.

“Tiger faeces are the size of large beetroots and have a characteristic pungent, musky odour,” he explained.

“Fresh tiger faeces are normally accompanied by urine sprays that smell like well-cooked basmati rice.”

Tigers are solitary animals, and use the spray to mark their territory – hence the presence of scat offered an insight into the species density in the area.

When the team compared its findings with data from camera traps, the group found the new system provided similar results but for just 7% of the cost.

Writing in the British Ecology Society journal, the team concluded: “The approach and models… permit rapid and cost-effective assessments of abundance to monitor the status of tigers at landscape scales.

“This information is vital for conservation investment, habitat management, planning development projects, formulation of policy and for law enforcement.”
